Generate .S files for syscalls. This has many advantages:

Browse Source 
- dependencies actually work (I need this to propagate some fixes
  in <machine/asm.h>)
- the cpp pipeline goes away, so errors can't leak out of it and
  an ANSI cpp is automatically used.
- it's simpler - standard rules get used instead of repetitive
  special rules.  (This showed bugs in the strip steps in the
  standard rules.  The wrong strip flag was also used for *.po
  here.)

Removed some ${ECHO}s and `@'s.  Normal make echoing of what is
being done is now not much more verbose than the echo messages
were, and is more useful.
